We libertarians are often argue that both the left and the right are equally guilty of stepping on key freedoms. We currently have an excellent example of that in the case of freedom of speech in broadcast media (radio and TV).
From the Right: New initiatives to crack down on "bad language" and sexual content in broadcast media, most famously driving Howard Stern to satellite.
From the Left: While bent out of shape about the right's crackdown on immoral speech, the left turns around and attempts a crackdown, via renewal of the Fairness Doctrine, on political speech. See hapless John Kerry decrying loss of the Fairness Doctrine here, and a more coherent history here.
Can't we just agree to allow everyone free speech and turn off what we don't want to hear?
